In the painting After Summer Rain, which was produced by Zhu Xuanxian on the theme of palm tree, the palm tree looks even more green after the rain, and the small joints of the palm tree are growing. The key point of the picture is a spider’s net destroyed by the rain, which wittily gives the meaning “after the rain”. The destroyed spider’s net and the small spider have not brought a sense of decay, but makes the picture more vivid, more profound and more exquisite, carrying a unique tone of life.
